What is the maximum speed for extended flaps in the CRJ 200?

In the CRJ 200, the maximum speed for extended flaps at 45 degrees is indeed 145 KIAS. This limitation is crucial because exceeding this speed can lead to structural damage to the aircraft or loss of control due to the aerodynamic effects caused by the flaps being deployed.

Understanding flap limitations, especially the maximum speeds for each flap setting, is vital for safe operation during various phases of flight, particularly during approach and landing. The correct answer highlights the specific flap configuration and associated limitations that pilots must adhere to, ensuring a safe flying experience in the CRJ 200.

For other options provided, 130 KIAS, 140 KIAS, and 150 KIAS do not accurately reflect the regulatory standards for the respective flap positions in this aircraft model, making those speeds inappropriate and unsafe for operational use.
